CORE-SUPPORT AND BEARING MEMBER.

Specification of Letters Patent.

Patented Sept. 10, 1907.

Application filed April 27, 1907- Serial N 370.704.

To all whom it may concern:

Be it known that I, WILLIAM FAIRCHILD, a citizen of the United States ofAmerica, and a resident of Albany, county of Albany, State of New York,have invented a certain new and Improved Core-Support and BearingMember, of which the following is a specification, reference being hadto the accompanying drawings, forming a part thereof.

Core supports and bearing members of the type to which this inventionapplies are employed in the making of castings containing holes for thereception of pintles and the like. A device of this character is filledwith a core of loam or other mold material, and is then set in the moldwith the pattern, beingleft in the mold when the pattern is withdrawn.The metal is then poured into the mold, a portion of the metal flowingaround the core support and bearing member and uniting solidlytherewith. When the casting has cooled and is removed from the mold, thecore of loam or other molding material is removed, with the result thatgood cleanbearings are formed in the casting. This obviates theexpensive drilling that would otherwise be necessary; gives a cleanhole, and further the metal of which the device is composed constitutesa lining which forms better bearing material than would the cast metalitself. 1

The present invention comprises an improved form of core support andbearing member which is simpler in construction and less expensive tomanufacture than articles of a similar nature which have beenconstructed in the past. It is composed of but a single piece struck upwith but a few operations from a blank.

In order that my invention may be fully understood, I will describe anembodiment thereof in detail, having reference to the accompanyingdrawings illustrating same.

In the drawings Figure 1 shows a portion of a stove including a door andsupport therefor in which core supports and bearing members embodying myinvention are employed. Fig. 2 is a view in detail of a blank from whichthe core support and bearing member is struck up. Fig. 3 is a view inside elevation of the core support and bearing member in process ofconstruction. Figs. 4, 5 and 6 are respectively side, end, andperspective views of the same when completed and ready for use.

The present device is particularly adapted for use in stove castings,and in Fig. 1 I have shown the same as so applied. In this figurereference character 11 designates a portion of a stove, and 12 a doorhinged thereto. The support 11 has bearing lugs 13 and the door 12 hassimilar bearing lugs 14 arranged complementary thereto. Pintles 15 passthrough openings in the lugs 14 and 13, whereby the parts are pivotallyconnected together; and each of the said lugs is provided with a coresupport and bearing member 16 for receiving said pintles, such devicesbeing illustrated in detail in the other figures. The device comprises acylindrical shell 17, a back plate 18 and connecting elements 19, and isformed from the blank which appears in Fig. 2. This blank comprises acentral portion having lateral or side Wings 20 and end portions 21,said end portions being connected with the main or body portion by meansof narrow necks 22. The side wings 20 are curved over to form thecentral bearing portion 17 while the end portions 21 are first bent atright angles to the central portion and then again at right angles, theportions 21 substantially meeting to form the back plate 18, while thenarrow necks 22 form parts of the connecting elements 19.

From the foregoing, and from an inspection of the drawings, it will beapparent that a device so constructed is an extremely simple one and isvery inexpensive to make. The device is used, as such devices aregenerally used, by filling the cylindrical portion 17 with molding sand,and then inserting the device in the mold with the pattern. When thepattern is removed the device is left in place so that it finallybecomes a a part of the casting, as above explained.

What I claim is:

l. A core support and bearing member comprising a single integralstructure having a cylindrical body portion and wings which are turnedover at right angles thereto and then again at right angles tothemselves, the latter portion substantially meeting and forming a rearplate, substantially as set forth.

2. A device of the character described comprising a single integralstructure composed of a thin sheet of metal, the blank of which haslateral wings 20 and end po1' tions 21 connected by narrow necks 22,said lateral wings 20 curved over to form a cylindrical member 17, theend portions 21 being folded over parallel with the cylindrical portionto form a back plate 18.

IVILLIAM FAIRCHILD.
